中文摘要：

以在水温28±3℃下饲养的黄鳝（Monopterus ablus）（37．35±0．89g）为研究对象，以酶学方法研究黄鳝不同免疫组织（血液、体表粘液、肝脏、肠道、肾脏、脾脏）中非特异性免疫相关酶（超氧化物歧化酶（SOD）、酸性和碱性磷酸酶（ACP、AKP）、补体C3、C4）的分布情况。研究结果显示，组织中SOD活性依次为；肝脏〉肾脏、脾脏〉粘液〉肠道〉血液（P〈0．05）：ACP活性依次为：脾脏〉肾脏〉肝脏〉肠道〉血液、粘液；AKP活性依次为：肾脏〉肝脏〉脾脏〉肠道〉粘液〉血液；补体C3的含量依次为：肝脏〉肾脏〉脾脏〉肠道〉血液、粘液；补体C4的含量依次为：肝脏〉脾脏〉肾脏〉肠道〉血液、粘液。由此可见，超氧化物歧化酶和补体C3、C4主要分布于肝脏中，碱性磷酸酶主要分布于肾脏中，酸性磷酸酶主要分布于脾脏中；而各种非特异性酶和物质在肠道、血液和粘液中也均有少量分布。

英文摘要：

The Monopterus ablus （average weight： 37.35 ±0.89 g） were bred in the temperature of 28 ±3 ℃. The tissue distribution of immune - related enzymes including the superoxide dismutase （ SOD）, alkaline phosphatase （ AKP）, acid phosphatase （ ACP）, complement eomponents C3 and C4 were examined with enzyme analytieal method. The results showed that ： The activity of SOD in different tissues was liver 〉 kidney 〉 spleen 〉mueus 〉 Intestine 〉 blood; the aetivity of ACP ranged as follows ： spleen 〉 kidney 〉 liver 〉 intestine 〉 blood 〉 mucus; the activity of AKP ranged as ： kidney 〉 liver 〉 spleen 〉 intestine 〉 mucus 〉 blood, the content of complement C3 was liver 〉 kidney 〉 spleen 〉 intestine 〉 blood 〉 mucus, and complement CA was liver 〉 spleen 〉 kidney 〉 intestine 〉 blood 〉 mucus. Those results indicated that the activities of SOD, ACP, AKP and the content of complement components （C3, C4） in liver, kidney, spleen was higher than that of other tissues.
